the 'ven w'o'l' o'e side 'befpi'e the balance w's done. To ciu'e this 'defe'c't is the object of myfinvention end I havefsoi've'djhe problem 'by teking `the`heate ge'se from 'the "fire t'o a point benje'th Tihe oven, di's'trihii't'ng `them over the between the t'p ef the even smd the top of with theltop of fbhe'pven. fl'ie 14, The fire-box' 'is eime'dfied with the isflues 14 and 15. The flues 12 and 14 are collectively equal in capacity to the flue 17, flue 15 or the flue 26. 'l This fiue 26 'leads from the port 21, With which it communicates, directly to the rear of the stove where it turns toward the fire-box side ,and communicates with a chimney flue 30.n rl`he fire-box side of this flue 26 has a port 27 adapted to efl'ect direct communication. between the top of the fireboxflue and thechimney. i

The front plate 31 of'the stove contains doors 32 and 33 Vfor the'oven and ashpit and a cleaning door 34 to allow access to the distribution fine' 16. A cleaning door 35 is al-o provided at the rearof the' stove in communication With a receptacle 86 having an inclined bottom 37 and into which'soot and particles of partially oonsumed fuel are precipitated.

The forward end of the fiue 26 is in-the fo'r'm of a'daniper 40, and a slidable damper 41 operated by a pull-red 4.2 controls the port 21 and a similar damper 43 operated by a. `pull-red 44. controls the port 27.

A 'damper-controlled port is located in the side wall 51 of the stove and'in a position slightly' below the g'rate, and the fireboir is;lin ed with fire-brick 52. J

The corner of the distribution flne 16 at eachside of the stove, (but not at the front andiback'), are cut elf by' plate's 55 andr respectirely to direct the flow froin the flue 17`to the fines 12 and 14.

'The space between the back-plate 6 of the oYen and -the'rear wall of the stove and surround'ng the fl'ue 17 and the `receptacle 36, vthe vspaceent offby the lates 55 and 56' and thespace between'the p ates 20 and 150 are. alll packed With asbestos or other heat insulating `material 'thus preventing radiatjion of 'any of the heat from the vfine 17 between Vits'en'dsjand enablin practically all the hot ga-see from the fire- 0x to be delive'red to the' distribution 'space 16.

In order to per-mit t e ready frequent Cleaning ofthe'si'de and top flues a scraper 190 o`f`inverted U-forrn and clasping the top and sides 'of the oven, has a pair ofrods 200 connected the'reto and projeeting through the front 32. .Bydrayvin 'this' seraper forward 'he'vs'ootandashesw ichj'collect'on the top and'sides 'oftheov'en are dislodged and pre cipitat'ed to'the 1distribution flne where they' may-'hej removed' by thev cleaning door 34'.

Then itf is l,desir'ed to have 'a direct draft upon thefirefrorn 'theohimney the damlper i 41 i 'closed andthe'daniper 43 opened w en the 'flow will he upjwardly throuxh the grate past the 4lnonthl', flue 17 to t through port' 2 7- andalong fljues 26 and 30 to the chimneandlwhen it is desii'ed to heatth oventhdamper '41 is opened and darhper f'cIoeedjfthus causing the draft to e space 28 distributin space 16, flues 12, 14 and 15, port 21 anc fiues 26 and 30 to the ehimney.

This particular arrangement of parts and flues seoures either a direct draft from the fire through the space beneath the stove top to the chimney or from the fire-box around the oven to the chimney and in the latter casethere is ractcally a uniform heating of all parts o the o'ven.

What' I clairn is as follows- 1 In a coolcing apparatus, the combination `with a heat generator and an oven; of a coniparatively large distributing ehamber beneath theoven; a 'downwardly extending flue atl the rearfi of 'the apparatus leading from the heat generator to the rearv of the heat distributing Chamber; a chimney connection; and flues leading from the distributing Chamber 'np each side of the oven to the chimney connection, substantially as described.

2. In a cooking apparatus, the combinw tion With a. heat generator located at one side thereof, and an oven, of a distributing Chamber beneath the oven; a fine at the rear of the apparatus and leading from the heat generator to the rear ofthe distributing Chamber; a top fiue'oo'mpletely covering the top of the oven and having a central port in its top; side flues at the sides of'theov'en and efl'ecting communication between the distrbuting chan'iberand the top fine; a chimney fine, and a flne leadino' from the central port of the 'to flue to the chimney fiue, snbstantially as' escribed.

v'3, In a cooking' apparatus the combination with a fire-box located at one side there of, andan oven; of a distributing Chamber beneath the oven; a line at the rear of the apparatns and leadingfroin the fire-boxto the' rear of the distributing chamber; a top fiu'e completely covering the top of the oven and having a central port in its to side fiues at the sides of the oven and e ecting communication between the distributing chainber and the top flue; a chimn'e flue; a fineleading lfrom the central port o the top filie to the chimney 'flne and havin a port in the side thereof toward the fire- Withinwhich the. last-rnentionedv fiue'is com tained, and dampersjcontr'ollin the orts 0x and al stove top covering thefire-box and' space 14, In a'jcooking a'pparatu', t 'ecorn ina? the fapparatus .and the said oven a flue above the said plate and communicating at one end With the central port therein and at its opposite end With the chimney connection, the said fine having a port in the side thcreof toivard the fire-box; a stove top covering the fire-box; the oven and the space containing thelast mentioned fiue, and dampers controlling the said ports, substantially as described.

5. In a eooking apparatus, the combination With a chimney connection, a fire-box located near the top of one side thereof and having a grate, and an oven located between and spaced from the fire-boX and the opposite side of the apparatus the said oven being spaccd above the botto'ni of the apparatus; a plate located above and spaced from the top of the oven and having central port; a fine leading from the fire-box to the space beneath the oven and having its intake end disposed in close proximit'v to the grate, a horizontal line above the said plate and comn'iunirating at one end With the central port therein and having a port in the side thereof toward the fire-box; a stove top covering the fire-box; the oven and the space containing the last-mentioned flne; dampers controlling the said ports; a chimney fine commnnicating With the chimney connection and the last-mentioned flne, substantially as dcscribed.

6. In a cooking apparatus, the combination with a chimney connectionl` a fire-box located. near the top of one side thereof and having a grate and an oven located between and spaced from the fire-box and the opposite side of the apparatus and the said oven being spaced above the bottom of the apparatusz a plate located above and spaced from the top of the oven and having a central port, a fiue leading from the fire-box to the space beneath the oven and having its intake end disposed in close proximity to the grate, a horizontal flne above the said plate and connnunicating at one end With the central port therein and having a port in the side thereof toward the fire-box, a stove top covering the fire-box, the oven and the space containing the last-Inentioned fiue, dampers controlling the said ports, a chimney flue communicating With the chimney connection and having a receptacle at its lower end for soot, etc., and a Cleaning door therefor, the said horizontal flue communicating at its rear end with the said last-mentioned-fiue, substantially as described.

7. In a cooking apparatus the combination with a chimney connection, a fire-box located at the top of one side thereof and having' a grate and having its outer side wall of greater height than its inner side wall; of an oven located between and spaced from the fire-box and the opposite side of the apparatns, the oven being spaced above the bottom of the apparatus and the oven having an arched top: a plate located above and spaced from the top of the oven and extending from the ton of the oven' and extending from the fire-box to the opposite side of the apparatns and parallel to the arched top and having a central port, a horizontal plate above the last-mentioned plate and extending from the top of the inner Wall of the fire-box to the opposite side of the apparatus and having a central port communicating with the central port of the plate first mentioned, a flue above the horizontal plate, a heat noncondneting packing Within the spaces surronnding the flue between the top of the oven and the back of the apparatus and between the upper archcd plate and the horizontal plate and in the Corners of the spaces beneath the oven, and a fire-brick lining for the fire-box, substantially as described.
